"Looking around the rest of the case, there is a 120mm normal exhaust fan with its own molex power adapter neatly wrapped up like its blower style counterpart. The fan also has a three-speed speed switch built into the back of the case again with the H, M, and L labels. Behind where the hard drives are installed is the main and only air intake slot, as you might have seen in the drive picture. The fact that it is passive is an impressive statement on Antec's part, and I am really interested to see what kind of temperatures this case achieves. As advertised on the display box, there is a dust filter over the intake that can be easily cleaned by simply pulling it out with the built in grips."
